If you are an R-1 Missionary and are receiving support from overseas, I want to encourage you to have your foreign supporters contribute directly to your R-1 employer.   That way, your R-1 employer can use that money to pay you, and then, at the end of the year, your R-1 employer will be able to give you a W-2 or a 1099 form.   You then can use those forms to file tax returns.   And, as I said last week, you want to be filing US tax returns each year reflecting income from your R-1 employer.  This will help you when you file for an extension of your R-1 or for a religious worker green card.
